Title: Improvements in hydraulic couplings
Inventor: MENNESSON MARCEL LOUIS
IPC: F16D33/00
Filed: 1954-01-26
Abstract: 746,104. Hydraulic clutches. SOC. D'APPAREILS DE CONTROLE ET D'EQUIPEMENT DES MOTEURS S.A.C.E.M. Jan. 26, 1954 [Jan. 29, 1953], No. 2390/54. Class 69 (2). [Also in Group XXXI] A. hydrokinetic coupling is provided with packing means at the place where a shaft splined to the runner extends through the casing, the packing means being spring-urged to form a liquid-tight seal when the coupling is at rest, but being loosened when the coupling is rotating. An impeller 1 forms an end wall of the coupling casing and is fast on a shaft 2 forming an extension of a crank-shaft 8 of an auxiliary engine for driving a cycle. A runner 3 is splined on a shaft 4 carrying a roller 11 bearing on the cycle tyre. The runner carries a packing ring 25 bearing against a ring 26 in the impeller 1. A sleeve 19 movable on shaft 4 is urged by a spring 23 against a ring 24 carried by the runner. A liquid-tight packing is thus provided. When the engine is running the oil in the coupling is forced against the periphery of the casing, and acts through a flexible diaphragm 18 to move the sleeve 19 against the action of spring 23. Contact between rings 24, 25 and the co-operating surfaces is therefore broken and friction consequently reduced. To allow starting of the engine by means of the shaft 4, the impeller 1 carries a pawl 29 cooperating with an abutment 31 on the runner so that the runner may drive the impeller. When the engine starts and the impeller speed exceeds that of the runner the pawl escapes from the abutment. When the runner speed reaches a certain value the pawl is retracted by centrifugal force out of the path of the abutment. To provide a positive drive at high speeds the pawl 29 is provided with a heel 33 which contacts the abutment 31 when the centrifugal force has retracted the pawl sufficiently.

Abstract: 456,048. Leading-in conductors for electric discharge apparatus. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Jan. 24, 1935, No. 2400. Void [Abridged as open to inspection under Sect. 91 of the Acts, July 26, 1935]. [Class 39 (ii)] An electric discharge device having a sealed evacuated envelope includes a metal portion through which at least one electrode lead or support is taken, the lead or support being supported by and insulated from the metal portion, and the insulating joint between the lead or support and the metal portion is closed in a vacuum tight manner on the side thereof remote from the interior of the envelope, whereby the vacuum seal is relieved of thermal and mechanical stress taken up by the insulating joint. In one form, a lead passes through a metal wall in an insulating bushing, which is rendered vacuum-tight by sealing material such as glass, enamel or sealing-wax, applied externally. In the form shown, the lead 3 passes through an insulating bushing 6, 7 and is screwed to a metal cap 10. The space between the cap 10 and a similar projection 9 on the wall is sealed up with glass 11. In a modification, Fig. 3 (not shown), the glass seal 11 is replaced by a porcelain cylinder screwed on to the lead 3 and coated externally at each end with metal such as copper. The parts 9, 10 are soldered to the coppered portions.

Title: Improvements in or relating to machines for applying color to a web
IPC: A24C5/56
Filed: 1945-01-31
Abstract: 602,736. Coloured cigarettes. FRIEDWALD, H. Jan. 31, 1945, No. 2454. [Class 130] [Also in Groups VIII, XXIV and XXXV] The middle portion c of a cigarette is coloured (preferably with aniline) leaving uncoloured bands d; e at the ends. In a continuous-rod cigarette making machine an uncoloured band is left along the edge of the paper web which is to be gummed. In the machine for coating the web, shown in Fig. 3, the colouring material is supplied to the paper web f as it is drawn from a spool 12 around a roller 14 by rubber plates 43, 44 on a roller 20 which is fed from a high speed roller 23, rotating in a reservoir 22, through an adjustable roller 24. To ensure that the cutter 11 of the cigarette making machine severs the web at the same point in relation to the coloured portion a regulator 17 (see Group XXXV) through which the web passes is provided adjacent the cigarette making machine. If the coloured portion is incorrectly located in relation to the severing mechanism the regulator causes rotation of a ring gear 38, forming part of a differential gear 31 through which the roller 20 is driven from the main drive shaft 90, and advances or retards the time at which the plates 43, 44 apply colour to the web. To prevent the plates smearing the web during adjustment the roller 20 has a loose driving connection (see Group XXIV) with its shaft 30, which allows the roller to be adjusted only when the recesses between the plates 43, 44 are in engagement with the web. When the roller 20 is rendered inoperative by moving a hand lever 75 to disengage a clutch 29, the roller 24 is swung away from the roller 20 by linkage 81-86 which closes an electric switch 87, 88 to start a motor 78 which keeps the rollers 23, 24 rotating. The web f may pass through a drying chamber before entering the cigarettemaking machine.

Title: A method of continuously obtaining concentrates from solutions
IPC: B01D9/00
Filed: 1951-02-05
Abstract: <PICT:0697992/III/1> Liquid mixtures are separated by freezing out a substantial quantity of one component to produce a crystal mush, passing the mush through an elongated container, the mush completely filling the cross-section of the container, passing in countercurrent to the mush a displacement liquid of the same composition as the solid portion of the mush, and withdrawing the liquid component of the mush at a point in the container intermediate the points of introduction of the mush and displacement liquid.  The displacement liquid may be obtained by melting the solid emerging from the container.  In Fig. 1, a mush, e.g. of fruit juice and ice, is forced by a screw 22 through a tube 15 which terminates in a space 16 provided with a heater 18, which may be a condenser coil of the refrigerator used for freezing the fruit juice, and an outlet 19 with spring-loaded valve 24.  Pressure developed by the screw 22 forces water produced by melting ice in the space 16 back through the crystal mush.  This water displaces concentrate in the interstices of the ice crystals and the concentrate is withdrawn at 46.  Excess water from space 16 passes off through the valve 24.  The screw may be replaced by a reciprocating plunger.  The tube 15 may be arranged horizontally or vertically.  The Specification refers to the concentration of various vegetable juices, wine, beer, solutions of salts, whey, skim milk and natural and synthetic latex.

Abstract: 1423819 Impregnating fibrous laminates; tubular laminates INSITUFORM (PIPES & STRUCTURES) Ltd 22 Jan 1973 [21 Jan 1972] 2913/72 Heading B5N [Also in Divisions E1 and F2]  The fibrous sheet of a laminate comprising a fluid-impermeable membrane, a fibrous sheet and means defining an air space adjacent the fibrous sheet is wetted out with resin by creating a partial vacuum in the air space to draw resin therethrough. Preferably the laminate is tubular and is held against the surface of a sewer pipe or mineshaft so that an impregnated lining is formed in situ, although the laminate may be impregnated before forming a lining therefrom. Fig. 4 shows a preferred laminate for forming a tubular lining, comprising polyethylene membranes 14, 20 a needled felt 16 and a fabric 18 made up of woven open-mesh polypropylene materials 18A, 18B held apart by polypropylene filaments 22 to define an air space. The fabric 18 may be replaced by honeycombs or other spacer means. Materials for layers 14, 16 are specified in Specification 1,340,068. The resin and the vacuum are applied via pipes 24, 26 (Fig. 3) respectively which extend between the laminate layers and contact the fabric 16 or the air space. The resin feed pipes 24 are provided at various levels around the periphery of the tubular laminate and have apertures along their length; they are supplied from a reservoir 38 via valves 40. The vacuum tube 26 is connected to a pump 44. In operation, the laminate is sealed at 28, 30 to air lock chambers 32, 34 and is inflated against the tube to be lined by supplying air under pressure through a pipe 36. With the pump 44 operative, resin is drawn through the pipes 24, the pipes at different levels being supplied in successive stages. The formation of air bubbles in the fabric between such stages is minimized by stopping the pump 44 between said stages, opening valve 48 and allowing resin to flow from a header tank 46 into a reservoir 42, thus forcing resin back into the fabric.

Hardenable synthetic resins are produced by (i) dissolving 1 mol. of boric oxide in 0À5-3À0 mol. of a molten phenolic component containing at least 65 mole per cent of a phenol having n positions per molecule capable of reaction with HCHO, solution being effected between 120‹ C. and the b.p. of the phenol; (ii) mixing the solution with 0À2 n to 1À0 n moles per mole of phenol of an aldehyde component containing at least 25 mole per cent of HCHO or an HCHO generator; and (iii) heating the resultant mixture. The reactive phenol, e.g. phenol or o-, m- and/or p-cresol, may be supplemented by another having no HCHO-reactive positions. The aldehyde component may contain other aldehydes, e.g. CH 3 CHO, C 2 H 5 CHO, benzaldehyde and furfural. Formaldehyde generators specified are paraformaldehyde, trioxan, tetroxan, a hemiformal of a primary or secondary alcohol, or a low M.W.polymethylol derivative of a phenol, urea or melamine. They may be assisted by the presence of a catalyst, e.g. hexamethylene tetramine, a Lewis acid, B 2 O 3 , P 2 O 5 , phosphoric acid or pyrophosphoric acid. The treatment with formaldehyde may be effected at 20-100‹ C. and will produce a novolak if 0À2 n-0À3 n moles of aldehyde is used or a resol if 0À3n-1À0 n moles is used. Step (iii) may be effected at 80-100‹ C. in the presence of a catalyst, e.g. hexamethylene tetramine, or an acid. The water of condensation may then be distilled from the product which may be used in a moulding composition. If a novolak, hexamethylene tetramine may be used to harden it. In examples moulding compositions are compounded from resins of the invention together with asbestos, fluorspar, zinc stearate and CaO.

Abstract: 657,271. Glass-to-metal seals. BRITISH THOMSON-HOUSTON CO., Ltd., and SCOTT, W. J. Feb. 3, 1949, No. 3005. [Class 36] Two metal rings 1, 2 having little flexibility are sealed together by an intervening mass of glass 3 having a thermal expansion matched to that of the rings, the rings forming part of, or being hermetically joined to, relatively flexible cylindrical metal walls 4, 5, which are integral with, or secured to, parts 10 of a vacuum-tight enclosure, which parts 10 are thus insulated from each other. The rings 1, 2 may be of rectangular crosssection, and are preferably made of an ironnickel-cobalt alloy suitable for sealing to borosilicate glass. The rings are hermetically joined to the walls 4, 5, which may be channel- or Z-shaped in cross-section, by welding as at 6 and brazing as at 7. Alternatively, the walls 4, 5 may be made integral with the rings 1, 2, Fig. 4. The parts are then assembled with a ring of glass between them and heated to cause the glass to flow between the adjacent surfaces of rings 1, 2. The glass may also be allowed to flow over the inner and outer surfaces of ring 2 to increase the creepage path. The inner surface of ring 1 may also be glass-coated by placing a second glass ring on the lower flange of wall 4, which, when heated, will flow down over the inner surface of ring 1 to unite with the glass 3. The assembly is finally welded as at 11 to the parts 10 of the enclosure, thus forming a hermetically sealed enclosure in which the parts 10 are insulated from one another. Specification 358,934, [Group XXIII], is referred to.
